Specification of Letters Patent.

Patented July 6, 1909.

Application filed February 21, 1908. Serial No. 417,206.

1'0 all whom it may concern:

Be it known'that I, Rorar. H. Donsn a citizen of the United States, residing at tiainesville, in the county of Cooke and State of .Texas, have invented certain new and useful Improvements in Sad-Iron-Edging lllachines, of which the following is a specification.

My invention relates to an improvementin machines for edging sad irons, and the object is to provide means for removing the rough edges from sad irons thereby making them smooth and giving them the desired shape. The invention relates to certain novel features of construction and combinations of parts which will be hereinafter described and pointed out in the claims.

In the accompanying drawings Figure 1 is a perspective view Fig. 2 is a View in side elevation; Fig. 3 is a longitudinal sectional new; Fig. 4 1s a top plan view; Fig. 5 is a detail view of one of the sliding blocks; Fig. 6 is a view showing the mechanism for making the frictional contact for operating the machine, and Figs. 7, 8, and 9 are views of the iron holder.

A, represents the frame, and 1 is a shaft jonrnaled in blocks 2, 2 adapted to. slide in guide ways 3, 3 on the frame. These blocks are connected by rods 4,4 which pass through one end of the frame. Coil springs 5 encircle these rods and bear against the blocks and a bar 6 connected to the end of the frame. At or about the ends of the rods an angle plate 7 is connected thereto. A cam 8 is mounted on the cross bar 9 of the frame and is adapted to enga e the angle plate 7 for sliding the blocks 2 1n the guides.

Mounted on the shaft which is journaled in. the blocks 2 is a gear wheel 11', which is adapted to mesh with a gear 12, which gear is adapted to engage a pinion 13 on the shaft 1 1 This shaft 14 is mounted on the frame. and carries a gear 15 thereon which meshes' with a worm gear '16 on the shaft 17. The gears 11, 12 and inion 13 have a hinged connection or gear )y means of bars 18 and 19. The bar 18 connects the gears 11 and 12, and a bar 19 connectsthe gear 12 and the pinion 13. These bars are really connected to the shafts 14 and 1 and are connected to the stud shaft 20 of the ear 12. Mounted on the other end of the shaft 1 is the sad iron holder 21. Thehead of the holder is prosquared end of the iron.

vided preferably with a groove 22 therein for the handle of the iron, and on each side of the plate are flanges 23. At one end the flanges are closed and have a V-shaped plate 21 on the upper surface and extending up through the closed end is a thumb screw 01' bolt 25 adapted to afford an adjustable sup port for the pointed end of the iron. Adjustable retaining plates '26, 26 are connected to projections 27, 27 of the flanges 23 adapted to bear against the sides of the iron to keep thesame in position. A similar retaining plate 28 is connected to one of the flanges 23 and is adapted to bear against the rear or The head of the holder is provided with a V-shaped offset portion 29, and pivoted thereon is an L- shaped lever 30 by means of a bolt 31. This lever is held under tension by means of a spring 32 hearing against one side of the head and the end of bolt. The lever is adapted to pass through an opening 33 in one of the flanges 23 and over the handle of the sad iron, thereby holding the iron in place. By the tension of the spring 32 the level is allowed a little play, whereby it can pass over any size of handle and holdthe same in position.

A wheel 34; is mounted on a shaft 35 journaled on the frame, and a former 36 in the shape of a fiat iron mounted on the shaft 1 is adapted to bear against the wheel 34 dnrmg the operation thereby causing the iron which is being operated upon to be ground or edged to the proper shape.

A shaft 37 mounted on the frame atone end is provided with a drivexpnlley 38, which is adapted to be connected to any source of power, and on the shaftis a friction wheel 39=adapted to engage a friction'disk 10 on the shaft 17 Wherebypower is transmitted to the shaft 17, causing the gear 15 to rotate and thereby transmitting motion to the gears 11 and 12, causing the sad iron holder to revolve and as the holderrevolves the former 36 revolves and engages the wheel 34, whereby the iron being ground receives its proper formation.

A lever 41 is connected to the frame having one end passing over a rod 42. A shaft 17 is mounted in a sliding block 43 on this rod 42 and is held undertension by means of a spring 44. By pressing the foot on the lever 11 the shaft 17 is caused to be shifted, making an engagement between the friction aria disk 4:0 and the friction wheel 39, whereby the power is transmitted to the operating parts.

The operation of this machine can be ascertained from the foregoing description, but to briefly recapitulate, the cam 8 is bperated against th angle plate 7, causing the blocks 5 to be d awn rearward, which causes the hinged gt ars to be drawn in the same direction due to the connection with the shaft 1. This operation brings the holder 21 out of contact with the emery wheel, whereby the lever 30 can be operated to release the iron which has been finished; removingit and replacing the same with an iron to be ground, when the lever is again thrown back over the handle thereby holding the iron in position. After the iron has been placed in position the cam 8 is turned releasing the blocks 5, thereby'permitting the iron to be operated upon to come into contact with the emery wheel. After this is in position the lever 41 is pressed or operated, causing the shaft 17 to be thrown over, causing a contact of the disk 40 and friction wheel 39. Power is then transmitted to the shaft 17 through the friction wheel 39 and disk 40, causing the gear 15 to revolve through its connection with the worm gear 16 on the shaft 17. The gear 15 will rotate the shaft 14:, causing the pinion 13 to revolve, thereby transmitting motion to thegear 11 through the. gear 12, thereby rotating the shaft The rotation of the shaft 1 causes the former 36 and sad iron holder 21 to be rotated. As the former 36 engages the wheel 34 the sad iron will receive its grinding or edging operation along the same surface as the surface of the former bearing on the wheel 34, whereby the proper shape 18 given to the iron being operated upon.

It is evident that more or less slight changes might be resorted to inthe form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I do not wish to be limited to the exact construction herein set forth, but

Having fully described my invention, what I claim as new and desire to secure by Letters Patentis 1.
